Unlike most Docker intros, this talk focused on the history of containers and the building of simple Dockerfiles. There was little mention of the differences between 'containers' and 'images'. While these items are fundamental to Docker, they can be a bit confusing and are ancillary until one dives deeper into other fundamentals.
